It provides 100% protection of the flue against rain, hail, snow, nesting birds, leaves etc. protecting it from damage while still allowing ventilation of the flue.

Left uncapped, disused chimneys are exposed to the elements, airborne debris and nesting birds and can be a major waste of energy via expensive heat loss from the home.

Fitting a CCap immediately solves these problems, potentially saving hundreds of pounds. Fitting takes seconds and can readily be carried out by your local chimney sweep or other contractor, with the necessary competence and equipment for roof access.

Why cap a disused chimney?

The Building Research Establishment (BRE) recommends disused chimneys should be capped off at the top with a ventilated capping. Research has shown that up to 80% of heat in a room is lost up the Chimney and least 35 litres of water comes down each chimney every year. C Cap Chimney Cappers are designed to cap off chimneys that are not being used. Where a disused chimney is left uncapped, it is open to the UK weather. Blockage of the chimney by nesting birds will not stop the rain getting in but it will tend to trap the moisture in the chimney by blocking ventilation and preventing the moisture from drying out.

Note:

Pots need to be in sound condition. Any cracked pot should either be replaced or suitably strapped to allow insertion of the CCap retaining wires.
